What made parliament stronger than the monarchs: it has 13 letters and the 3rd letter is l

The Bill of Rights http://en.wikipedia.org/wiki/Bill_of_Rights_1689

To find the answer to this question, we need to look for a word that has 13 letters and has the letter "L" as its 3rd letter. Let's go through the process step by step:

Step 1: We need to find a word with 13 letters.
Step 2: The 3rd letter of the word should be "L".

Now, let's go through a list of words that fit these criteria:

1. Parliament - 10 letters (not a match)
2. Spiderman - 9 letters (not a match)
3. Independent - 11 letters (not a match)
4. Chandelier - 10 letters (not a match)
5. Monarchists - 11 letters (not a match)
6. Backgrounds - 11 letters (not a match)
7. Shorthand - 9 letters (not a match)
8. Bloodstream - 10 letters (not a match)
9. Maladjusted - 11 letters (not a match)
10. Reinforcement - 13 letters (a match!)

So, the word that fits the criteria is "Reinforcement." However, it is worth noting that this word does not directly answer the question about what made Parliament stronger than the monarchs. The influence and power of Parliament relative to the monarchs developed over time through various historical events and changes in the governance structure.
